Bhote Koshi
The Bhote Koshi is the upper river course of the Sun Kosi, known as Poiqu in Tibet. It is part of the Koshi River system in Nepal.
A western tributary of the upper Dudh Koshi is also called Bhote Koshi.
River course
The headwaters of Poiqu and Bhote-Sun Koshi River are located at the Zhangzangbo Glacier in Tibet. The river flows out of the Lumi Chimi lake. When entering Nepal, it is called Bhote Koshi. Further downstream, from the village of Bahrabise onwards, it is called Sun Koshi.
Hazards
In July 1981, a sudden ice avalanche caused a Glacial Lake Outburst Flood in the moraine-dammed Zhangzangbu-Cho Lake in the headwaters of the Bhote Koshi. The ensuing debris flow destroyed bridges, and sections of both the Arniko and the Nepal–China highways.
Names and etymology
Nepali: भोटे कोशी; Chinese: 波特科西; pinyin: Bōtè Kēxī
In Nepali language, the word "bhoṭe" or "bhoṭiyā" means Tibetan; and the word "kosi" means river.
Tourism and sports
The Bhote Kosi is used for both rafting and kayaking. It is the steepest river rafted in Nepal, with a gradient of 15 m per km. Bungee jumping or swinging over the Bhote Kosi has been described as the ‘ultimate experience’.
